Abstract: 1386187 Towel dispenser NEUCO APPARATEBAU AG 23 Jan 1973 [28 Jan 1972] 3320/73 Heading A4G A web-form hand-towel dispenser comprises a delivery roller 5 by which hand-towel 7 is guided from a supply 6, a wind-up roller 16 for used handtowel, electric motor-driven driving devices for driving the rollers 5, 16, the roller 16 being drivable both in the wind-up direction and the opposite direction, and means actuable directly or indirectly by hand to switch on the drive for the roller 5 and the drive for the roller 16 to drive the roller 16 in said opposite direction. The dispenser also comprises means for switching off the drive to the roller 16 after unwinding a predetermined length of hand-towel from the used hand-towel roll, means for switching off the drive to the roller 5 after delivery of a predetermined length of handtowel, a timing device, means for switching on the drive to the roller 16 to drive it in the wind-up direction after the expiry of a predetermined time, and means for switching off the drive to the roller 16 after winding up a length of hand-towel corresponding to the sum of the hand-towel lengths previously unwound from the used hand-towel roll and the delivery roller 5. As described the rollers 5, 16 are driven by electric motors 12, 24 via gearing 9, 10, 14 and 19, 21, 22, and worms 13 and 23 respectively. In the start position the exposed portion of the web 7 is tight against the lower part 3 of a casing having slots 8, 18 for exit and entry of the web. When the web 7 is pulled the gearing causes the worm 13 to move axially and so operate a switch 15 to cause the motors 12, 24 to operate to feed web out of the slots 8 and 18. Instead of the switch 15 a push-button, light barrier, proximity, or contact switch may be used. After a predetermined time the motors 12, 24 are stopped, e.g. by switches operated by cams or by a measuring roller 44. After a further time the motor 24 is operated in the reverse direction to wind up the used towel portion until it is taut enough to operate a switch 53, 52 and stop the motor, or a timing device may be used. If the end of the web is reached the motor 24 is stopped by e.g. a light beam switch. A bar 38 acts to smooth the towel web when the motor 24 is winding up the web but is withdrawn by a lever 42 when the web is being fed out from the roller 16. A switch 57 may be operated by arms carrying the measuring roller 44 to operate an alarm when the web is nearly used up. In alternative embodiments there is a single electric motor driving the delivery and wind-up rollers via intermittently operable connections.

Title: Improved process and apparatus for the removal of hydrogen sulphide and other noxious constituents from gases containing them
IPC: C10K1/08
Filed: 1923-02-06
Abstract: 210,382. Koppers Co., (Assignees of Ramsburg, C. J.). Jan. 24, 1923, [Convention date]. Washing plant and processes; materials for purifying.-In the purification of gases such as coke-oven gas from sulphuretted hydrogen and hydrocyanic acid by a multi-stage process such as that described in Specification 207,488 by treatment with a solution of sodium carbonate followed by a revivefying treatment of the solution, the final stage of washing out the last portions of the impurities from the gas is effected with a solution freed from sulphuretted hydrogen preferably by treatment with ferric oxide. Sodium carbonate solution withdrawn from the revivification step of the first purification of the gas which may be as described in Specification 170,572, is fed to an agitation vessel 2 by a pipe 1 and is mixed with a suspension of iron oxide from a " Dorr thickener " or the like 10 through a pump 13 and pipe 6. Compressed air is injected from branches 3 of a pipe 4, and the liquid may also be agitated by mechanical devices. The temperature is raised to about 50‹ C. by a steam coil 5. The mixture passes by a pipe 7 which receives compressed air by pipes 8, 9 to the " thickener " 10 where the suspended matter is separated and returned through the pump 13, and the clear solution is passed by a pipe 11 to a tank 12 in which it is cooled and is then passed through a pump 16 and pipe 17 to jets 18 for irrigating the final gas scrubbers 14, 15 from which the used liquor returns by a pipe 19 to the primary gas purification apparatus or to the apparatus 2. The operation of the pump 16 may be controlled by a float in the tank 12 as described in Specification 207,488. From time to time sulphur may be removed as a scum, and the iron oxide when it contains a large quantity of sulphur, may be, withdrawn and treated for the extraction of sulphur and the regenerated iron oxide returned to the process or replaced by fresh oxide. Specification 190,131 also is referred to.

Title: Improvements relating to piezo-electric devices and the manufacture thereof
IPC: H03H3/02
Filed: 1946-02-05
Abstract: 607,453. Etching. PHILIPS LAMPS, Ltd. Feb. 5, 1946, No. 3572. Convention date, Feb. 12, 1945. [Class 100(ii)] [Also in Group XL(c)] The manufacture of a piezo-electric crystal element includes immersing the element in an etching solution while simultaneously agitating the solution at a supersonic frequency. A piezo-electric plate 13 such as quartz or tourmaline, which has been ground to dimensions slightly greater than those desired, is placed so as to form a partition across an insulating tank 10 containing an etching solution comprising 40 per cent hydrofluoric acid or 25 per cent ammonium difluoride. Electrodes 16 immersed in the solution are connected to a valve oscillator, Fig. 2 (not shown), tuned to a desired supersonic frequency. The crystal then becomes the frequency determining element of the oscillator, and etching takes place until the dimensions of the crystal are sufficiently reduced to give the desired frequency as measured by known means. By this process, the crystal is dissolved while subject to physical agitation thus removing all fragments left by the initial grinding process, and microscopic crystals which are non-permanently attached. This is said to eliminate frequency drift due to ageing of the crystal.

Title: Slowdown control circuit for pattern tracing apparatus
IPC: B23Q35/123
Filed: 1959-02-03
Abstract: 872,749. Electric copy-milling machines. CINCINNATI MILLING MACHINE CO. Feb. 3, 1959 [April 16, 1958], No. 3760/59. Class 38 (6). In an electric copy-milling machine of the kind in which a stylus explores a template and the X and Y movements of the template are controlled by resolving an A.C. speed control signal into two components by means of a selsyn resolver controlled by the stylus, stylus deflections also cause the speed control signal to be reduced to slow down the template movement until the error signal is reduced, whereupon the speed control signal is increased exponentially by an integrating circuit. The template 10 is mounted for movement along X and Y axes by hydraulic servomotors 92. The stylus 20 is universally pivoted at 19, and its upper part is coupled to the armature of an E-type transformer 25 by a ball and double-cone joint 21. A slight deflection of the stylus in any direction is arranged to raise the armature to the " null " position of the transformer, and greater deflections cause increasing output. This output is applied via one secondary of a transformer 41 to a phase-sensitive detector and servo-system to adjustably rotate a resolver 80. The rotor of the resolver 80 has a winding 79 energized via a push-pull amplifier 57, 58 from a speed control voltage tapped off a potential divider 48. The stator of the resolver 80 has two windings at right angles, the outputs of which control the X and Y servomotors via phase-sensitive detectors and amplifiers so as to cause the template to move past the stylus. The template is held in contact with the stylus by applying the stylus deflection signal to a second rotor winding 100 on the resolver 80 to provide a component of movement at right angles to the normal feed. The stylus deflection signal is also applied via another secondary on transformer 41, and a cathode follower 105 to a voltage-doubling rectifier 116, 117, 118, 119 to provide a positive bias to control an amplifier 123. The anode resistor 125 of the amplifier 123 is included in the grid/cathode circuit of the feed rate signal push-pull amplifier 57, 58 so the feed rate signal applied to the resolver 80 is reduced as the amplitude of the stylus deflection signal increases. A diode 121 is connected in series with the grid of amplifier 123, and this is shunted by an integrating circuit 131, 132 which charges rapidly when the stylus signal increases, but discharges at a pre-set rate when the stylus signal decreases, thereby limiting the rate of acceleration of the feed motors and preventing hunting on abrupt directional changes. Reference has been directed by the Comptroller to Specification 810,838.

Patent GB-1124472-A (GB)
Title: Surface coverings
Inventor: SINDEN GEORGE
IPC: C08J9/236
Filed: 1966-01-27
Abstract: A floor or surface covering is produced by (1) applying an adhesive patternwise on to part of the surface of a polyvinyl chloride sheet, (2) contacting the surface of the sheet with polyvinyl chloride chips or granules which contain a blowing agent e.g. azodicarbonamide, whereby the chips or granules adhere to the areas of the surface of the sheet to which the adhesive has been applied, (3) pressing the chips or granules into the surface of the sheet, and (4) heating e.g. at 165 to 200 DEG C., to decompose the blowing agent in the chips or granules to effect foaming.  The adhesive may be a polyvinyl chloride plastisol, polyacrylate, polyvinylacetate, or ethylene-vinyl acetate copolymer.  A transparent wear layer may be applied e.g. of polyvinyl chloride, as a spreadable composition or a preformed calandered layer to the sheet between steps (3) and (4).  The wear layer may have a thickness of from 0.005 to 0.0025 inches.  The sheet used in step (1) may be a sheet which has been previously prepared by application on to a substrate of a spreadable polyvinyl chloride plastisol followed by heating to effect gelation; the substrate may be removable after gelation.  The chips or granules may have an average particle size of less than 0.2 inches.  The chips or granules may contain a stabilizer-kicker.  In step (2) the sheet may be moved through a U-configuration, the chips or granules being held in the well provided by the sides and bottom of the "U".  Heating may be effected at a temperature of 140 to 165 DEG C between steps (2) and (3) to effect at least partial setting of the adhesive and softening of the sheet.  In step (3) the material may be passed whilst not between rollers.  The term "polyvinyl chloride" includes vinyl chloride homopolymers and copolymers.  The polyvinyl chloride sheet may be bonded to a suitable substrate e.g. woven and non woven fabrics, paper felt, asbestos paper, woven hessian fabric, and woven hessian with needled jute fibres. Substrates which may be removable from the product after gelation e.g. silicone impregnated paper, or a conveyor treated with a release agent e.g. a silicone or PTFE, may be used.
